My company sells a lot of after market products for the big three and the guys that are seeing improved mileage around here are doing the exuast delete intake change and a good programor on average they see a decent fuel mileage increase driving solo but not much of an increase pulling.
There's a nationally known diesel shop in the Peoria area that does these up-grades. They work with a local dealer that will still cover the warranty as long as the up-grade didn't directly cause the damage. While I'm on the road I would loose this small safety net. Right now I have enough faith in this diesel, I'm not going to worry about it too much. I just stopped by their shop today to see when they could do the work and what they wanted to do. They said for best results they recommended the following:

#1 remove and replace the exhaust with a Mega-flow or efe system (down pipe back)
#2 cold air intake
#3 exhaust fluid delete
#4 EGR assembly removed
#5 New programer (Sparten)

With these changes we'll run cooler, stronger and get better mpg WITHOUT adding a bunch of black smoke. This will give me about 965 ft pounds of torque when turned up all the way.

I think I'll do all of it BUT the EGR valve for now and do that later. They said Ford has been having some issues with their EGR clogging for some reason although I haven't had any problems at all with mine.
